The present invention relates to cleats for football and similar sportsfootwear and to the method of making the same.

It is a well known fact that previously various types of stud cleatshave been marketed, to some extent varying as to shape and materialsused. By way of example it may be mentioned that hard rubber has beenused, but experience up to now has proved that the only stud widelyadhered to by the overwhelming majority of players is the i one made ofleather and secured to the sole by means of a nail.

However, studs made of leather have several disadvantages. They arerather easily worn out and must therefore be exchanged frequently, andbeing secured to the sole by nails which are bent on the inside, theywill have to be forced loose by means of tongs, whereby the sole will betorn. Little by little, the sole will make a very insecure base for thenew studs, and it may even be completely useless. The comparativelylarge number of holes through the sole will impair the stiffness of thesole in such manner that the studs cause a pressure on the feet of theplayers. Furthermore, the holes contribute to absorption of moisturefrom the ground, whereby the sole will become soft and weakened. Thiswill make the insole uneven and bossed because of the pressure from thestuds.

The present invention has for its object to reduce these disadvantagesby inserting into the sole a metal plate to which the studs are securedby means of screws. This means of attachment has been used as far asstuds made of hard rubber are concerned, but has not been applicable tostuds made of leather. It is a fact that the leather stud together withthe screw must form one compact piece, and this has hitherto not beenobtainable by simply screwing loose disc-shaped leather pieces to thesole. According to the present invention this problem has been solved bysecuring the leather disc to the screw by subjecting the discs to anaxially actuated pressure causing a permanent reduction of the thicknessof same. i

The procedure according to the invention is, by way of example,illustrated on the accompanying drawing forming a part hereof andwherein:

Fig. 1 is a top plan view of an assembly provided during an initial stepof a method of producing cleats according to one embodiment of thepresent invention;

Fig. 2 is a side elevational view, partly broken away and in section, ofthe assembly of Fig. 1;

Fig. 3 is a top plan view of a completed shoe cleat formed from theassembly of Figs. 1 and 2;

Fig. 4 is a side elevational view of the cleat of Fig. 3;

Fig. 5 is a top plan view of an assembly provided during an initial stepof a method of producing cleats according to another embodiment of thepresent invention;

Fig. 6 is a side elevational view of the assembly of Fig. 5;

(Cl. 12142) s Fig. '7 is a top plan View of a completed shoe cleatformed from the assembly of Figs. 5 and 6; and

Fig. 8 is a side elevational view of the completed cleat of Fig. '7.

Figs. 1 and 2 illustrate the first stage in the procedure 5, in whichseveral leather discs, which prior to this have been provided with acentrally located hole 2 have been threaded on to the screw 3. Upon thisthe leather discs and the screw are placed in a press, whereby they willtake a shape as shown in Figs. 3 and 4, where the thickness has beenconsiderably reduced. The example shown indicates how a conical stud ismade. In this case, leather discs of different diameter are used, and bypressing them in a mould having a conical inner wall, the finished studwill get an even surface.

During the pressing operation the leather discs are pressed so forciblyagainst the screw that the constituent parts form one compact piece.When the stud is to be screwed into the sole it will be possible to turnthe stud without using a screw-driver. As will be understood, the studmay be screwed in position by means of tongs.

In Figures 5 to 8, inclusive, is shown a stud, which is made in asimilar way, but in which case there is fashioned on the end of the studa covering plate 4 which is secured by means of tacks 5 to the otherdiscs. As a matter of course, the outer disc will be worn out first, andthis may be replaced by a new covering plate without necessitating theremoval of the stud itself.

In case cylindrically shaped studs are to be made, the procedure is thesame, with the exception that, in that case, the discs to be used havethe same diameter and that the pressing operation takes place in a mouldhaving a cylindrical inner wall.

I claim:

A process of making studs for football and other types of sportsfootwear consisting of forming a central hole in each of a plurality ofleather discs, passing a screw through the registering holes in saiddiscs and subjecting said discs while threaded on the screw to axialpressure to compress and consolidate the same.
